Re: network manager doesn't find cdc-wdm0

It seems some debug output was cut off. In another log i noticed the 
following:

-----------------------------------------------------------------------------

-----------------------------------------------------------------------------

From another source it seems there should be a device plugin named 
'NMWwanFactory', which is missing here. Could this be the reason?
